If you’re going to get everyone’s attention, make sure it’s to support the mission, not for personal gain. Think through the problems that are plaguing your project. Write down thoughtful, insightful solutions. Present them to leadership. Those solutions may not work, but the process will be at the very least educational. Don’t nag, but be persistent, choose your moment wisely, be professional, and don’t hold back about the consequences if you don’t succeed. Tell them you’re passionate about making this job work, but if you can’t solve these issues then you’ll probably quit.
